According to the doctor, US President-elect Joe Biden twitched his ankle after slipping while playing with his dog.
In a brief statement, Biden’s office said the incident took place on Saturday and that the 78-year-old man was examined by a bone expert on Sunday “because of a lot of caution”.
Biden later visited an orthopedic specialist in Newark, Delaware. His doctor, Kevin O’Connor, said Biden was twitching in his right leg, and although “the initial X-rays reassure him that there is no obvious fracture,” he will receive a CT for further review.
Journalists traveling with him were kept on a bus and could not see that he had entered the building.
Biden will be the oldest U.S. presidential post when they take an oath next year, and his health is likely to be monitored by both allies and opponents.
He played with Biden Major, his family’s two German shepherds – he is expected to be the first rescue dog to live in the White House.
Biden and his wife, Jill, adopted Major in 2018 after acquiring their first dog, Champot, after the 2008 election. Bidens said they are bringing their dogs to the White House and also planning to get a cat.
Biden often dismissed age-related questions on the campaign trail. In December, he published a medical report saying he was taking statin pills to keep his cholesterol levels healthy, but his doctor considered him “healthy, strong” and “fit for successful presidency duties”.
